Fatal error: Class 'PHPMailer' not found in

Fatal error: Class 'PHPMailer' not found in C:\wamp\www\sendemail.php on line 13

Dies ist Zeile 13:

$mail = new PHPMailer();

Habe ich auch schon recherchiert, und Sie sagen, Sie müssen diese:

require_once('class.pop3.php');
require_once('class.phpmailer.php');
require_once('class.smtp.php');
require_once('PHPMailerAutoload.php');

Aber ich habe bereits diese und Sie befinden sich im gleichen Ordner wie sendemail.php aber immer noch der gleiche Fehler.
